NAME
       nvme-effects-log - Send NVMe Command Effects log page request, returns
       result and log

SYNOPSIS
       nvme effects-log <device> [--human-readable | -H] [--raw-binary | -b]
                               [--output-format=<fmt> | -o <fmt>] [--verbose | -v]

DESCRIPTION
       Retrieves the NVMe Command Effects log page from an NVMe device and
       provides the returned structure.

       The <device> parameter is mandatory and should be the NVMe character
       device (ex: /dev/nvme0).

       On success, the returned command effects log structure will be printed
       for each command that is supported.

OPTIONS
       -H, --human-readable
           This option will parse and format many of the bit fields into a
           human-readable format.

       -b, --raw-binary
           This option will print the raw buffer to stdout. Structure is not
           parsed by program. This overrides the human-readable option.

       -o <fmt>, --output-format=<fmt>
           Set the reporting format to normal, json or binary. Only one output
           format can be used at a time.

       -v, --verbose
           Increase the information detail in the output.

EXAMPLES
       o   Print the effects log page in a human readable format:

               # nvme effects-log /dev/nvme0

       o   Have the program return the raw structure in binary:

               # nvme effects-log /dev/nvme0 --raw-binary > effects_log.raw
               # nvme effects-log /dev/nvme0 -b > effects_log.raw
